Osteocephalus sangay

The Sangay casqued tree frog (Osteocephalus sangay) is a frog in the family Hylidae. It lives in Ecuador.

Body
The adult male frog is 40.3–41.3 mm long from nose to rear end.  The adult female frog is 45.3-52.8 mm long.  The skin on the frog's back is green or brown in color.  It can have bumps made of keratin protein or dark marks.  The tops of the legs and middle are light brown with darker brown marks.  There is a large dark brown mark on the head.  The sides of the head have a cream-colored stripe.  There is yellow color on the skin outside the eye.  The ear is green in color or dark brown in color.  The sides are light green, cream-colored, or brown with brown or black marks.  The skin of the belly is brown with darker brown marks or lighter brown marks.  The pupil of the eye has an olive green ring around it.  The iris of the eye is bronze in color with black lines.

Name
Scientists named this frog for the place they first found it: Parque Nacional Sangay.  It is in Ecuador's Morona Santiago province.  The word "sangay" comes from the Shuar language word "samkay." This word is for volcanoes.

Home
This frog lives in forests that have never been cut down on the east sides of the mountains.  Scientists have seen it at night, sitting on plants 2 m above the ground.  Scientists have seen it between 1551 and 1795 meters above sea level.  Scientists think this frog has young in streams, but no scientist has written about seeing the eggs or tadpoles as of 2022.

Scientists have only seen this frog in one protected park, Sangay National Park (Parque Nacional Sangay).

Danger
Scientists do not know whether this frog is in danger. They think people changing the paces where the frog lives could be a problem, mostly if the frog lives outside Parque Nacional Sangay.
